Hi, Yes it still runs ok, but requires an electric starter to start it when hot.
I thought the ABC engines were designed in such a way that the piston and cylinder expanded at the same rate to maintain the fit at running temperatures? Is this not the case?
Regards Angus
This is somewhat true. When it stops running, the aluminum piston head will start cooling faster than the chrome plated brass sleeve. They can't contract at the same speed because the brass and chrome will hold heat longer than aluminum.
